Three rapid fire drop offs (the third delivery was just being brought in when the camera stopped recording):

DH returns to the nest at 9:11 in the morning, whichsuggests* that she didn't come back to the nest before sunrise like usual.

One owlet standing tall to look out the hole; the other four are at the back looking up. At lower right, #5 can be seen laying down, which is how he usually sleeps.

Two drop offs. #5 is at the back, barely visible, scrounging around on the floor for scraps:

*A technical note is relevant here.
The nest cam is solar powered. During
the early spring, before the trees leafed out, the camera battery would get run down during the night from
use, and it would then get charged back up to 100% during the day. Then the trees leafed out at the same time
that the owlets stopped sitting still ever, so the battery is no longer keeping up
with both the use and the lack of sunshine hitting the solar panel. Thus, the camera
is dying at some point every night which means that we're missing hours of action, so I don't know for sure, but it appears that DH quit sleeping in the box with the rowdy owlets yesterday at 1 p.m. She moved out last year as well when the owlets started bouncing off the walls, and started sleeping in a nearby pine tree with Boyle.

This was an important day. This was the day that the owlets were bouncing off the walls so much that DH moved out of the nest in the middle of the day. It was that bad.

In this video, you can see how crowded the nest box is getting, and how rambunctious the ruckus. (The noises you hear outside are those of a graduation ceremony at the park a block away.)

Here, it looks to me like this is #5 working his wings a bit:

And the final flapping session that drove DH out (she left 5 minutes later):

DH did return to the nest box that evening, and made the particular kinds of noises she always makes when she's been away from the owlets for longer than average (as in, an entire hour instead of just a few minutes.) In this case, she was gone for over 5 hours:

The other milestone was that an owlet successfully made it up into the hole and sat there momentarily before (apparently, to my anthropomorphizing eye) seeing something frightful out in the world, and jumping back into the nest to hurriedly bury its head under a sibling. We have a healthy bat population so there are 6 or 8 of them whizzing right past the nest box every evening. My guess is that a bat is what scared the owlet.

#5 picks up a scrap of wing from the floor. He seems to spend much more time than the others scrounging around on the floor for scraps. Perhaps his runt status will result in him being more resourceful.

A drop off:

Owlets clamoring for the hole; #5 is jostled to the back:

An owlet almost makes it up into the hole:

A drop off, and a good look at little #5:

Another drop off, and this time, I'm pretty sure that's #5 getting the moth:

I've received some complaints about the lack of excitement in the owl videos. The thing about nest cam videos is that this is nature, the way it's unfolding in the real world, and sometimes it's calm. There are periods of time where not much happens, or the juicy action is hidden from view, and there aren't many car chases or bike jumps, but for those of you lamenting that fact, I can, finally, offer at least a bit of gore. In this video, DH feeds a bloody bird head to an owlet -- look for the beak at :46 -- and (bonus!) does it in daylight, which means it's in color:

At this point, DH is spending most of the night out of the nest, only entering and staying when she has something big, like a bird, that she needs to tear up for the babies. The majority of the feedings, though, are quick drop offs of small things like moths and cockroaches, during which the parents don't even enter the nest. They just land in the hole, stick their head in, give someone a dead thing, and take off:

Here, Boyle delivers a dead bird to DH, who is in the nest, and she mantles (sorry) and starts tearing the bird up to feed it to the babies:

This is another long one with not a lot of action. One of the parents has dropped off a dead bird and the owlets don't entirely know what to do with it:

Often when DH is feeding the owlets, she mantles around them and they (and the food) are almost entirely hidden. Here is what we'll call a half-mantle, allowing a partial view of the owlets at 12 and 10 days:

This is a long (4 minute) feeding sequence with decent visibility and both parents:

In this series, the owlets (at 12 and 10 days) have been left a bird carcass to do with what they may. They sleep on it, drag it around, sleep on it some more, and finally wake up and start to tear into it.

#5 in the upper right, eyes closed. Note the size difference between #5 (ten days old)
and its siblings (12 days old.)

by Trina

#5 is the temporary name (suggestions are welcome) for the fifth owlet who hatched 2 days later than its siblings and is considerably smaller, weaker, and easier to miss when feeding. We want ALL the owlets to survive, which is not likely, we know, but for now they are all still alive, and for now, I'm paying particular attention to whether #5 is getting fed during deliveries. Feedings are fairly frenetic, making it hard to see exactly what's going on, but once in a while we get a decent glimpse of #5 in the hubbub:

Here, #5 is on the left, struggling with a piece of something dead, while DH feeds the other owlets in the upper right corner:

Here, #5 makes a move and gets fed:

#5 gets food:

Here, a mere 22 minutes later, #5 gets fed again. You can hear his little beak clicking against the nest box wall as he struggles to get something down:

Every morning I awake to dozens of nest cam videos from the night. The camera is motion triggered, so when there is motion, it starts recording; when the motion stops, it stops recording. If I'm awake and can answer the alert that I get when there is motion, I can make a longer video. When I'm asleep, though, the camera is on and off throughout the night, recording in short 20 to 30 second bursts of activity. Most of the clips are nearly the same sequence of parent feeding, hopping up to the hole to sit with his or her wings directly in front of the camera for a few seconds -- you definitely have to be patient with the lengthy views of an out-of-focus owl wing (ah, first world problems) -- and then leaving to go find more food. Feed, sit, leave (FSL). Return in a minute, or 3 minutes, or 25 minutes. Feed, sit, leave. Repeat. There are variations on the theme. Sometimes Boyle brings DH a kill, giving it to her as she sits in the hole. Sometimes he delivers a kill to her inside the box and she dispenses it to the babies, tearing off small pieces for them. Sometimes he delivers to the babies inside the box. Sometimes he gives her food on a branch outside and she takes it into the owlets. Either way, they are both working so very hard, all through the night, doing some version of the FSL over and over and over:

In these next 2 videos, DH does an FSL-return-FS, and then receives a delivery from Boyle, all within one minute:

#5 with a moth? lacewing? It looks like he doesn't actually succeed at eating it, though. It gets hard to see once DH hops up into the hole to sit, but it looks like one of the larger owlets dives for the bug at 1:30 after #5 left it laying on the floor:

On the night of the 3rd, the nest cam caught this interesting footage. As usual, DH comes in with a kill, feeds the babies, and hops up to sit in the hole. At the one minute mark, she leaves and comes back quickly to feed again. Then, just as she's about to leave the second time, something outside apparently startles her. Here's how she reacts:

I went outside to see if I could tell what was going on but didn't see anything because, well, it was dark. The next morning, though, our local Great Horned Owl was sleeping in a tree not even a full block away, so that may well have been what scared DH. It's both really amazing and really worrisome to have a GHO in the neighborhood. It is, of course, such a treat to have wildlife like that in our busy little downtown neighborhood, but we'll be pretty unhappy if the GHOs eat our beloved WSOs.

When the terrors of the night aren't interrupting normal activities, the parents are in and out of the nest all night long feeding the five hungry little fluffs. In the last couple of days, feedings have been getting increasingly frequent and increasingly frenzied:

In this video, feeding proceeds as usual, and then the babies react to a firecracker:
